Why do some people hate Taylor Swift?

Taylor Swift is suing fans who sold her trademark merchandise on Etsy. These items included Taylor Swift dolls, candles with song lyrics on them, and nail decals. She has also trademarked certain phrases that feature in her song lyrics. She has trademarked, "This Sick Beat."

Swift seems to go to great lengths to protect her property. She also tends to jump from one relationship to the next, and when it is over, she always plays the injured party, especially in her music. Even, some people, (not me) get annoyed that her cats have their own twitter.
